PRESSURE APPLYING DEVICE Filed Feb. 23, 1960 INVE'NTOR ATTORNEY ireStats 3,030,654 PRESSURE APPLYENG DEVICE Romuald Migneault and FernandW. Migncault, both of 332 St. Andre St, St. Gatineau, Quebec, CanadaFile-d Feb. 23, 1969, Ser. No. 10,132 1 Claim. (Cl. 1691) This inventionrelates to a pressure applying device for applying sealing pressure toclosure panels such as windows, doors, and the like.

In sliding panel construction in building structures, such as thesliding glass panels of windows, it is desirable practice to providemeans for resiliently urging the panel into snug fitting engagement witha wall of the groove in which it is slidably mounted in order to preventthe oc currence of drafts and to avoid rattles and the like.

It is an object of this invention to provide a pressure applying devicefor a sliding panel which is of simple, inexpensive construction, whichmaintains the panel in substantially draftproof relation to its mountingstructure, which holds the panel substantially free from vibration, andwhich readily permits normal sliding movement of the panel.

The invention will be described with reference to the accompanyingdrawing, in which:

FIGURE 1 is a plan view of a device in accordance with the invention inassociation with a sashless window structure,

FIGURE 2 is a bottom plan view of the device, and

FIGURE 3 is an end elevation of the device.

The device of the present invention comprises a base plate 1 and achannel-shaped member 2 mounted thereon. The member 2 forms with thecentral portion of the base plate a rectangular housing 3. Conveniently,the member 2 may be fixed to the plate 1 by means of edge tabs on member2 which project through complementary opemngs 5 in the base plate andthe ends of which are upset. The housing 3 has an open end 6, itsopposite end being closed by a wall 7.

Slidably mounted in housing 3 is a bracket 8 having a pair of opposedears 9 at one end thereof and in which a roller 10 is rotatably carriedas by means of a pin 11. Sliding movement of the bracket is limited bymeans of a lug 12 carried by the bracket and projecting through a slot13 in the base plate portion of the housing. The roller-carrying portionof the bracket projects outwardly through the open end 6 of the housingand a peripheral portion of the roller is disposed outwardly of thebracket ears 9 and of the housing 3 in all positions of the bracket withrespect to the housing.

Means are provided for resiliently urging the bracket and roller in anoutward direction and comprises a spring 14 in the housing having oneend engaging a flange 15 fixed to the bracket and its other end engaginga nut 16 carried by a screw 17. Screw 17 has a slotted head 18 seated inan opening 19 in housing end wall 7 whereby the screw may be rotatedfrom outside the housing by applying a screw driver thereto. The spring14 is retained in 3,036,554 Patented Apr. 24, 1962 position at one endby a stud 20 carried by the flange 15 and at its other end by the endportion of screw 17. The nut 16 is restrained from rotation byengagement with the walls of the housing.

The lateral portions of base plate 1 constitute mounting flanges 21.Each flange is preferably provided with a slot 22 and a hole 23.

FIGURE 1 illustrates one mounting installation of the device by way ofexample. A pair of sashless window panels 24 are shown as slidablymounted in a groove 25 in a frame 26. The device of the presentinvention is mounted on the frame 26 with roller 10 in pressure-applyingengagement with one of the panels 24 thereby to press the panels againstone wall of the groove 25. In installing the device, screws 27 aredriven through the slots 22 into the frame and the device moved intoengagement with the panel 24 and the bracket and roller retracted intothe housing until pressure is applied to the panel by means of thespring 14. When the device has been placed in desired relation to thepanel, the screws 27 are tightened to hold the device in such position.Finally, the device is positively locked in position by driving nails 28through the holes 23 into the frame. The tension of the spring 14 isthen adjusted, if required, by applying a screwdriver to the screw 17.

There has thus been provided a pressure applying device which may bereadily and positively installed in operative position and which may beconveniently adjusted while in such operative position.

We claim:

A pressure applying device for sliding panels comprising a rectangularhousing having side walls, an open end, an end wall closing the oppositeend thereof, and laterally projecting mounting flanges, a bracketslidably mounted in said housing, means limiting the sliding movement ofsaid bracket, a roller carried by said bracket and having a portion ofits periphery projecting through said open end of said housing and lyingoutwardly thereof, resilient means urging said bracket and roller in adirection outwardly of said housing comprising a spring in said housinghaving one end seated on said bracket, a screw having a head seated onsaid housing end wall and a nut on said screw, said nut being inengagement with the other end of said spring and constituting a seattherefor, said nut having engagement with said side walls of saidhousing to prevent rotation of said nut, said end wall having an openingtherein and said screw head having a slotted portion projecting throughsaid opening, said slotted portion being accessible exteriorly of saidhousing for application of rotative motion thereto to rotate said screwand cause said nut to travel therealong and thereby adjust the tensionof said spring.
